EWC validator node install scripts

EWC and Volta affiliate validator node installation scripts.

Keep a scratch file ready to collect outputs in - You'll need them

Steps

See our Atlassian wiki for installation instructions

Shared secrets

The following files contain secrets that are used on the validators:

• .secret => Contains the password for the ethereum private key Is accessed by parity and nodecontrol to send transactions to the chain
• .env => Contains the individual second channel password in the SFTP_PASS variable. Used by nodecontrol
• files in signer-data/ used by the signer to store the signers encrypted private RSA key for signing telemetry packets.

The following values are considered as public keys in .env:

• VALIDATOR_ADDRESS => Ethereum address of the validator account. Used by signer and nodecontrol for identification.
• TELEMETRY_INGRESS_FINGERPRINT => SHA256 fingerprint of the Ingress TLS certificate. Ingress presented cert needs to verify against the fingerprint.
• SFTP_FINGER_PRINT => Fingerprint of the SSH hostkey when connecting to the second channel.
